All Five DNA and RNA Nucleobases Found in Ryugu Asteroid Samples

Scientists have detected all five fundamental nucleobases—adenine, guanine, cytosine, thymine, and uracil—in pristine samples from the asteroid Ryugu, returned by JAXA's Hayabusa2 mission. Published in Nature Astronomy, this discovery provides strong evidence that key ingredients for life were widespread throughout the early Solar System, enhancing our understanding of life's origins.
